Nintendo Revealed Why There Are Holes On Famicom Cartridges

Famicom cartridges are much different from their American counterparts, but there was one particular difference that has been a mystery for years. Instead of indentations that were used to snap the cart in place, Famicom cartridges have holes. Surprisingly, this is something that Nintendo never explained, until now. In an interview with Japanese website Afternoon News, they revealed that the Famicom cartridges had holes on the top because “they were just part of the design”. Here’s the conversation in full:

Afternoon News: ‘I believe there are holes on the top of [Famicom] cartridges. Do you know what kind of meaning they had?’

Nintendo: ‘Yes, to be honest, they were just part of the design.’

Afternoon News: ‘Um, these aren’t holes made during the molding or the assembly?’

Nintendo: ‘That’s correct. They’re just [part of the cartridge’s] design.’

Afternoon News: ‘Then, the holes on the front and the back of Irem’s cartridges are also design?’

Nintendo: ‘That’s correct. Similarly, that’s the design.’
